Compass is a web app written in plain HTML/CSS/JS. It uses DeviceOrientationEvent and geolocation to show a smartphone's GPS coordinates and polar orientation.
Open compass.ki9.us on a smartphone with a compass. Hold the phone level and it should show your direction.
No, not really. Results may vary. As of this writing, Firefox and Chrome browsers handle the DeviceOrientation spec differently. It's only been tested on Chrome for Android.
- When the screen is rotated, the image gets rotated 90 degrees. I don't know how this could be fixed.
The images used in this app were labeled for reuse with modification:
- The main compass image is from Wikimedia Commons
- The icons are adapted from an image found on goodfreephotos.com
